Secondary Security Screening Selection

Secondary Security Screening Selection or Secondary Security Screening Selectee, known by its initials SSSS, is an airport security measure in the United States which selects passengers for additional inspection. People from certain countries are subject to it by default. The passengers may be known as Selectee, Automatic Selectee or the Selectee list. The size and contents of the list fluctuates and is a secret, although the Transportation Security Administration has stated there are tens of thousands of names on it.

The Selectee list has been cited by civil liberties groups to be infringing on privacy rights and potential for racial and ethnic discrimination.
